During his Cali Christmas set, Chris Brown calls out Karreuche Tran and says he's single once more.

After existing in on-againoff-again territory for the majority of the year, Chris Brown and Karrueche Tran appear to have called things off again, only this time, things got a little ugly. During his performance at Cali Christmas last night, Breezy called Tran a "bitch" and said he was single once again.

TMZ has a video (below) of the moments in question, in which Brown asked if there were any single ladies in the house, then responded, "I'm single too. Fuck that bitch." While this is no way to treat an ex, it's better than beating the shit out of her and bashing her head against your dashboard.
